TECHNICAL DATA

NORMS

DIN ISO 1711-1 (Assembly tools for screws and nuts - Hand wrenches - Part 1: Combination open-end and ring wrenches - Technical requirements)

The DIN ISO 1711-1 standard establishes the technical and performance requirements for hand wrenches used in the assembly of screws and nuts, specifically covering fixed open-end wrenches, ring wrenches, and combination wrenches. This standard is crucial to ensure that these tools meet minimum standards of mechanical strength, durability, and dimensional accuracy. It defines criteria for material hardness, resistance to torsion under specific loads, and tolerances in the openings of the jaws, ensuring a proper fit to the fastener and minimizing the risk of tool deformation or rounding of the nut or screw during use.

DIN 3113A (Metric combination wrenches - With angled jaw)

The DIN 3113A standard specifically focuses on metric combination wrenches that have a fixed jaw on one side and an angled ring jaw on the other. This specification details the precise dimensions of both jaws (the fixed and the angled), the angle of the ring (generally 15° to facilitate access to fasteners in tight spaces), and the nominal length of the wrench. The "A" in the designation refers to this particular design of combination wrench with the angled ring jaw. By complying with DIN 3113A, it ensures that the wrench will have the correct measurements to work with metric screws and nuts, while also providing the expected functionality and ergonomics to reach hard-to-access areas, all while maintaining the quality and performance standards defined by other complementary standards such as ISO 1711-1.
